Conclusions
-
1.
We have synthesized a series of optically active substitutedα-aminoethylphosphonic acids and their ethyl esters.
-
2.
The yield of products from the condensation of aliphatic ketones with diethyl phosphite and ammonia depends on the order of introduction of the reactants into the reaction.
